BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sutera plant, botanically known as Sutera cordata and hereinafter referred to by the name ‘WINSUSNOBL’.

The new Sutera plant is a product of a planned breeding program conducted by the Inventor in Alajuela, Costa Rica and Carleton, Mich. The objective of the breeding program is to create new freely-branching and trailing Sutera plants with numerous large blue-colored flowers and high temperature tolerance.

The new Sutera plant originated from a cross-pollination conducted by the Inventor in November, 2016 in Alajuela, Costa Rica of Sutera cordata ‘Scopia Gulliver Blue’, not patented, as the female, or seed, parent with Sutera cordata ‘MegaCopa Blue’, not patented, as the male, or pollen, parent. The new Sutera plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Carleton, Mich. on Nov. 1, 2017.

Asexual reproduction of the new Sutera plant by terminal vegetative cuttings in a controlled greenhouse environment in Zeeland, Mich. since Dec. 11, 2017 has shown that the unique features of this new Sutera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sutera have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WINSUSNOBL’. These characteristics in combination distinguish ‘WINSUSNOBL’ as a new and distinct Sutera plant:

-   -   1. Low mounding to outwardly spreading and trailing plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit; dense and bushy plant form.     -   4. Early and freely flowering habit.     -   5. Large violet blue-colored flowers.     -   6. Long flowering season.     -   7. Good garden performance.

Plants of the new Sutera can be compared to plants of the female parent, ‘Scopia Gulliver Blue’. Plants of the new Sutera differ primarily from plants of ‘Scopia Gulliver Blue’ in the following characteristics:

-   -   1. Plants of the new Sutera are more vigorous and stronger than         plants of ‘Scopia Gulliver Blue’.     -   2. Plants of the new Sutera are more trailing than plants of         ‘Scopia Gulliver Blue’.     -   3. Plants of the new Sutera are more freely flowering than         plants of ‘Scopia Gulliver Blue’.     -   4. Plants of the new Sutera have larger flowers than plants of         ‘Scopia Gulliver Blue’.     -   5. Plants of the new Sutera are more tolerant to high         temperatures and drought than plants of ‘Scopia Gulliver Blue’.

Plants of the new Sutera can be compared to plants of the male parent, ‘MegaCopa Blue’. Plants of the new Sutera differ primarily from plants of ‘MegaCopa Blue’ in the following characteristics:

-   -   1. Plants of the new Sutera are more vigorous and stronger than         plants of ‘MegaCopa Blue’.     -   2. Plants of the new Sutera are more trailing than plants of         ‘MegaCopa Blue’.     -   3. Plants of the new Sutera are more freely flowering than         plants of ‘MegaCopa Blue’.

Plants of the new Sutera can be compared to plants of the Sutera cordata ‘G13340’, disclosed in U.S. Plant Pat. No. 29,037. In side-by-side comparisons, plants of the new Sutera differ primarily from plants of ‘G13340’ in the following characteristics:

-   -   1. Plants of the new Sutera are more vigorous and stronger than         plants of ‘G13340’.     -   2. Plants of the new Sutera are larger than plants of ‘G13340’.     -   3. Plants of the new Sutera have larger flowers than plants of         ‘G13340’.     -   4. Plants of the new Sutera are more freely flowering and flower         more continuously during the summer than plants of ‘G13340’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Sutera plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Sutera plant.

At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘WINSUSNOBL’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘WINSUSNOBL’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Sutera production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after propagating rooted cuttings and were six weeks from planting rooted cuttings when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
